A liquid chromatographic method with post-column derivatization for the determination of biogenic amines in wines is proposed. The method is based on the separation of amines by ion-pair chromatography using sodium heptanesulfonate (SHS) and on-line labeling of analytes with 1,2-naphthoquinone-4-sulfonate.

A liquid chromatographic method for the determination of aniline in cyclamate sweeteners based on a pre-column derivatization with 1,2-naphthoquinone-4-sulfonate (NQS) is proposed. Aniline traces were extracted from the cyclamate samples using dichloromethane. After solvent evaporation, the dry residue was derivatized
